can be used. Multiple values can be set separated by a space
within one string (e.g., <i><span data-if="hdevelop" style="display:inline">'cts_rts dtr_dsr'</span><span data-if="c" style="display:none">"cts_rts dtr_dsr"</span><span data-if="cpp" style="display:none">"cts_rts dtr_dsr"</span><span data-if="com" style="display:none">"cts_rts dtr_dsr"</span><span data-if="dotnet" style="display:none">"cts_rts dtr_dsr"</span><span data-if="python" style="display:none">"cts_rts dtr_dsr"</span></i>).
If and what
kind of parity check of the transmitted data should be performed can
be determined by <a href="#Parity"><i><code><span data-if="hdevelop" style="display:inline">Parity</span><span data-if="c" style="display:none">Parity</span><span data-if="cpp" style="display:none">Parity</span><span data-if="com" style="display:none">Parity</span><span data-if="dotnet" style="display:none">parity</span><span data-if="python" style="display:none">parity</span></code></i></a>.  The number of stop bits sent is
set with <a href="#StopBits"><i><code><span data-if="hdevelop" style="display:inline">StopBits</span><span data-if="c" style="display:none">StopBits</span><span data-if="cpp" style="display:none">StopBits</span><span data-if="com" style="display:none">StopBits</span><span data-if="dotnet" style="display:none">stopBits</span><span data-if="python" style="display:none">stop_bits</span></code></i></a>.  Finally, two timeout for reading from
the serial device can be set.  The parameter <a href="#TotalTimeOut"><i><code><span data-if="hdevelop" style="display:inline">TotalTimeOut</span><span data-if="c" style="display:none">TotalTimeOut</span><span data-if="cpp" style="display:none">TotalTimeOut</span><span data-if="com" style="display:none">TotalTimeOut</span><span data-if="dotnet" style="display:none">totalTimeOut</span><span data-if="python" style="display:none">total_time_out</span></code></i></a>
determines the maximum time, which may pass in <a href="read_serial.html"><code><span data-if="hdevelop" style="display:inline">read_serial</span><span data-if="c" style="display:none">read_serial</span><span data-if="cpp" style="display:none">ReadSerial</span><span data-if="com" style="display:none">ReadSerial</span><span data-if="dotnet" style="display:none">ReadSerial</span><span data-if="python" style="display:none">read_serial</span></code></a>
until the first character arrives, independent of the actual number
of characters requested.  The parameter <a href="#InterCharTimeOut"><i><code><span data-if="hdevelop" style="display:inline">InterCharTimeOut</span><span data-if="c" style="display:none">InterCharTimeOut</span><span data-if="cpp" style="display:none">InterCharTimeOut</span><span data-if="com" style="display:none">InterCharTimeOut</span><span data-if="dotnet" style="display:none">interCharTimeOut</span><span data-if="python" style="display:none">inter_char_time_out</span></code></i></a>
determines the time which may pass between the reading of individual
characters, if multiple characters are requested with
<a href="read_serial.html"><code><span data-if="hdevelop" style="display:inline">read_serial</span><span data-if="c" style="display:none">read_serial</span><span data-if="cpp" style="display:none">ReadSerial</span><span data-if="com" style="display:none">ReadSerial</span><span data-if="dotnet" style="display:none">ReadSerial</span><span data-if="python" style="display:none">read_serial</span></code></a>.  If one of the timeouts is set to <i>-1</i>,
the system waits an arbitrary amount of time for the arrival of
characters.  If both timeouts are set to <i>0</i> the system
doesn't wait and returns the available or none characters.  Thus, on
Windows systems, a total timeout of <a href="#TotalTimeOut"><i><code><span data-if="hdevelop" style="display:inline">TotalTimeOut</span><span data-if="c" style="display:none">TotalTimeOut</span><span data-if="cpp" style="display:none">TotalTimeOut</span><span data-if="com" style="display:none">TotalTimeOut</span><span data-if="dotnet" style="display:none">totalTimeOut</span><span data-if="python" style="display:none">total_time_out</span></code></i></a> + n
<a href="#InterCharTimeOut"><i><code><span data-if="hdevelop" style="display:inline">InterCharTimeOut</span><span data-if="c" style="display:none">InterCharTimeOut</span><span data-if="cpp" style="display:none">InterCharTimeOut</span><span data-if="com" style="display:none">InterCharTimeOut</span><span data-if="dotnet" style="display:none">interCharTimeOut</span><span data-if="python" style="display:none">inter_char_time_out</span></code></i></a> results if n characters are to be read.
On Unix-like systems, only one of the two timeouts can be set.  Thus, if
both timeouts are passed larger than -1, only the total timeout is
used.  The unit of both timeouts is milliseconds.  It should be
noted, however, that the timeout is specified in increments of one
tenths of a second on Unix-like systems, i.e., the minimum timeout
that has any effect is <i>100</i>.  For each parameter, the
current values can be left in effect by passing
<i><span data-if="hdevelop" style="display:inline">'unchanged'</span><span data-if="c" style="display:none">"unchanged"</span><span data-if="cpp" style="display:none">"unchanged"</span><span data-if="com" style="display:none">"unchanged"</span><span data-if="dotnet" style="display:none">"unchanged"</span><span data-if="python" style="display:none">"unchanged"</span></i>.</p>
